JOHN PETERMAN AND SYDNEYSMITH, OE SENECA FALLS, NEW YOEK.

CARPET-STRETCH'ER.

SPECIFICATION forming part of Letters Patent No. 272,468, dated February 20, 1883.

Application filed November 14,1882. (No model.) 7 v In the drawings, Figure l is a-perspective view of our improved carpet-stretcher in position. Fig. 2 is a longitudinal vertical sectional view thereof. Fig. 3 is a front end view.

Referring to the drawings, A designates a cross-bar having teeth B on its under side,

and provided with two ibrwardly-extending, convergent rods or braces, O G, to the outer ends of which are pivoted two parallel plates 1) .D, by a cross pin, E. These plates are preferably curved forward, as shown, and have pivoted between their tops a rearwardly-extending lever, F, having a pointed or camshaped end, G.

H is a rearwardly-extending pawl, which is pivoted between the plates D D under the lever F.

I is a longitudinal ratchet-bar having a pointed head, J, and ratchet-teeth K along its upper edge. The bar Iis arranged between plates D D under the pawl H, and also passes through a guide or staple, L, on top bar, A.

The operation and advantages of ou-rinvention will be readily understood and appreciated. The pointed head J of the ratchet-bar I is first driven into the floor near the wall, and the cross-bar Ais moved back to the rear end of bar I. Then by working lever F its pointed end engages the teeth of bar I and draws the cross-bar A toward the pointed head of the latter. The carpet is thus drawn and stretched toward the wall by the engaging teeth of the moving cross-bar A, and the latter is held from backward movement by the pawl H.

We claim as our invention The combination of a headed ratchet-bar, a toothed cross-bar having a guide or staple for the ratchet-bar, convergent bars or braces extending from the cross-bar, swinging plates 'pivoted to the ends of the convergent bars, a

pawl pivoted to the said plates, and an operating-lever pivoted to the platesabove the pawl and having its end engaging the rackbar, as set forth.

In testimony that we claim the foregoing as our own we have hereto affixed our signatures in presence of two witnesses.

JOHN PETERMAN. SYDNEY SMITH.
